💡 How do internal spring formers stop soft metal tubing from flattening when making tight radius turns?
The quick trick relies on placing a stiff wire core inside the hollow wall before flexing the metal.
- Sliding the support rod all the way down prevents inner collapse during aggressive curve pulls
- Pulling the backup rod clear after shaping keeps the passageway totally open for fluid flow
- Grabbing the handy kit saves shop floor trips because five sizes handle most common pipe runs
- Cooling friction heat on stainless lines or chilled copper coils stops work hardening and cracking
